The Pamela Webb Architectural Collection contains the professional files, architectural drawings, artwork, and photographs of an architect working primarily in Portland, Oregon. Materials date largely from the latter quarter of the twentieth century, but extend into the early twenty-first century. Professional files include information about Webb's career (resumes, portfolios, etc), money-making endeavors, correspondence, press coverage, community involvement, proposal bids, and architectural projects.

Architectural renderings within the collection appear in different mediums—in diazo prints, on thin wax paper, and on white copy paper. These renderings document Webb's architectural projects (including her student work).

Significant projects include: Eastbank Esplanade, Forest Heights residential community, Austen Row attached homes, Warm Springs Early Childhood Learning Center, and Marian Abram's Children's Wing in Mittleman Jewish Community Center. The collection's photographs illustrate the construction and finished products of many of Webb's project designs.

Webb's provided artwork depicts a variety of subjects—from human forms to abstract designs to building ideas. In addition to drawings on paper, some of Webb's artwork is etched in metal or Plexiglas. Multiple sketchbooks also appear within the collection.
